4 Claims.

My invention relates to a railroad car moving device, particularlyadapted for moving railroad cars on sidings and the like.

The prime object of the invention is to provide a car moving devicewherein means are provided to operate a clamp to secure the device to arail and means to operate a lever against the wheel of a car to move thecar on the rails.

A further object of the invention is to provide means for creatingsufiicient power while the device is moving a car to thereafter advancethe device in direction of the moved car for a subsequent operation.

A further object of the invention is to provide an improved fluid poweractuated railroad car moving device.

A further object of the invention is to provide a device having fluidpressure means to clamp the device to the rail of a. track, and fluidpressure means for pushing a car associated with means for creatingpower while the car is being pushed to subsequently slide the device indirection of the car when the power operating means for actuating thedevice is released.

In the drawings:

Figure l is a side elevation illustrating the invention applied inposition to move a car on a track.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a sectional View taken on the line 3-3 of Figure 1.

Figure 4 is a side elevation of a modified form of the invention.

Referring now to the drawing, specifically to Figures 1 and 4, thepresent invention is shown in operative relation to a portion of arailroad car truck I to which is journalled the usual flanged wheel 2mounted on the track rail 3.

The present invention, referring to Figure l, which comprises a fluidoperated assembly 6 which includes a base 5, that is adapted to beseated on, and releasably clamped to the track rail 3. This base 5,preferably, straddles the rail 3 by means of lateral guide flanges 8 anda vise-like clamp assembly '1 which includes a clamp member 8 that isfixed to one side of the base 5, and a clamp member 9 that is mounted ona pivot Iii on the opposite side of the base Fixedly mounted on the base5 is a fluid pressure assembly which includes a cylinder l l operativelycontaining a piston is which has a piston rod i2 extending beyond thecylinder and transversely of the base 5 and is pivotally connected tothe lever I5 of the clamp member 9. Thus,

when fluid such as air, is supplied to the cylinder H through the airline i i, the piston I3 and rod I2 are forced towards the lever I5 ofclamp member 9, causing the clamp member 9 to press against the adjacentside of the rail 3, and pulling the fixed clamp member 8 against theother side of the rail, thereby clamping the rail between the clampmembers 8 and 9.

A lever i6 is pivotally mounted at its lower end on a cross-pin l1supported on the base 5, said lever being pivotally connected at itsupper end to a piston rod I8 that is connected to a piston whichoperates within a cylinder I9. A fluid supply line 26 extending from asuitable source (not shown) of fluid under pressure is connected to amanually operated control valve 21 which controls a hose line I l thatextends to a T-connection 28 with the cylinder i9 and an extension I4running to a coupling I! with the cylinder II. The valve 2 is ofconventional construction and includes an escape outlet 29.

A roller 29 is journalled within lever I6 (see Figure 2) for engagingthe periphery of wheel 2. The roller is formed with a groove 2 l toembrace the flange 2| of the car wheel, the flange 2I and the groove 2|forming a guide to prevent lateral displacement of the lever duringoperation.

A bracket 22 having a hook-like member 23 for engaging the journal box24 of the car truck I is connected to the end of the base 5 by a coiledspring 25 which is connected at one end to the bracket 22, and at theopposite end to the base 5 as by means of the cross pin ll. This springpulls the base 5 and the lever is toward the wheel 2 when the pushingaction of the cylinder I9 has been completed. Thus while movingthe car,spring 25 is tensioned and therefore is creating power to set the devicefor a subsequent operation.

In operation, the bracket 22 is hung over the journal box 24 of the cartruck I, and the base 5 is mounted on the rail 3, as illustrated inFigure l with the roller on lever I6 bearing against the wheel 2, whichforces thepiston rod down into the cylinder I 9. Air is supplied throughthe supply line 26 to the control valve 21, which when actuated, admitsair through the hose I4 and. T connection 28 into cylinder I9 and onthrough the extension I4 and coupling I I into cylinder II of the clampassembly 1. This air pressure draws the clamp members 8 and 9 againstthe rail clamping the base securely thereto. Simultaneously air is fedinto cylinder I9, and piston rod l8 forces the lever I6 toward the carwheel in the direction of the arrow in Figure 1, forcing the wheel 2forwardly and along the track 3, the

roller 20 riding on the periphery of the wheel 2 to reduce friction andguide the lever.

When the piston within cylinder I9 reaches the end of its travel, thevalve 21 is released, whereupon the air is released from the cylindersl9 and H through the valve escapement 29.

Valve 21 is of the standard make, which allows air to pass in onedirection from the line 28 when the valve is operated, and the supply ofair is cut off when the valve is released, permitting air to escape backthrough line H, thus exhausting air from said cylinders.

When the air is exhausted from said cylinders, the clamp member 9 isreleased freeing the clamp assembly from the rail and permitting thespring 26, at this time under tension, to move the base 5 toward thewheel, which movement causes lever l 6 to return the piston rod [8within the cylinder l 9 ready for the next application of air pressure.

In Figure 4 I have illustrated a modified form of the invention, whereinthe lever 16 is replaced by a lever 30 pivotally mounted at 32, betweenears 3| extending upwardly from the base 5. This lever 30 is operated bythe air cylinder 33 through the piston rod 34, which is pivotallyconnected to one end of said lever by a pivot 35, the cylinder beingpivotally supported by a pivot 36 on the bracket 31 of the base 5'.

A wheel engaging roller 38 is journalled on the other or free end of thelever 30.

In the operation of this modified form of the invention when air isapplied, the roller 38 of the lever 30 contacts the wheel 2, while theclamp I secures the base to the rail, and the cylinder 33 pulls thepiston rod 34 against the lever 3|, forcing the wheel 2 forward. Air tooperate the lever and clamp is supplied through the hose line 39 from acontrol valve, such as the valve 21. As in the preferred form of theinvention immediately the air pressure in the cylinder is released theclamp is released from the track and the power created in the springsnow under tension moves the device toward the car, and the lever 30 isreturned to normal position ready for a subsequent operation.
